CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 602,342, dated April 12, 1898.

Application led October 27,1897. Serial No. 656,538. (No model.)

the United States, residing at East Fairiield,`

in the county of Columbiana and State of Ohio, have invented certain new and usefulV Improvements in Car-Couplings; and I do hereby declare the following to be a full, clear,

and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention` has reference to a novel construction in a car-coupling, the object being to provide a coupling in connection with which the ordinary link is used, but which couples automatically.

The invention consists in the features of construction hereinafter described and specifically claimed.

ln the accompanying drawings, forming part of this specification, Figure 1 is a vertical longitudinal section` of a coupler constructed in accordance with this invention. Fig. 2 is a transverse vertical section with the coupling-pin elevated. Fig. 3 is a similar view with the coupling-pin at the lower limit of its movement. r

Referring now to said drawings, l indicates the draw-bar, and 2 the draw-head, which are of any approved construction in their gen eral structural features. The upper side'of the draw-head is Open, while in the lower wall of the draw-head is a slot 3v to receive the lower end of the pin 4. This vcoupling-pin 4 is provided with an enlargement 5, forming downwardly-facing shoulders 6, that are adapted to rest upon the link 7, as shown in Fig. 3,

l for the purpose of holding the link in a horizontal position.

At the rear end of the draw-head is the outwardly-extending projection 8, having an inclined front face that forms a rest or support for the coupling-pin when the latter is elevated. At each side of the draw-head and at the rear end thereof are the notches 9, that form bearings for the pivoted bar 10. This bar 10 is providedat its ends with a journal resting in said bearings and is also provided with arms 11, to the outer ends of which the ,tion even when the coupling-pin is not resting thereon.

It is seen from the foregoing description that the pin can be raised orlowered by means of the handle 12 and that in coupling automatically said pin can be raised until it rests against vthe upright or support 8. In

this position it stands at an inclination with the lower end of the pin high enough to permit the link to enter, while the impact between the couplers on the two cars as they come together in coupling will throw the pin forward, so that it falls through the link and the slot 3 inthe bottom of the draw-head.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

A car-couplin g comprising a draw-head having an open upper side, a llongitudinal slot in the lower wall thereof, bearings at the rear end of the draw-head for the support of the coupling-pin when raised, a pivoted bar resting in said 'bearings and provided with parallel arms, and a coupling-pin pivoted between said arms and provided with an en-
